Suggested sound cards for auditory stimulation

Hi all, I’m using PsychoPy to present visual and auditory stimuli to mice. My plan for the auditory stimulation is to present brief (say, 500ms) sounds, including prerecorded ultrasonic (<65 kHz) vocalizations, using some kind of 192 kHz DAC (e.g. a PCIe sound card, or an USB audio interface). This stereo output will be fed to a TDT SA1 stereoamplifier, after which one channel will be drive an ultrasonic-capable speaker and the other will feed directly to NI-DAQ to record the presented waveform…
